SODA-WATER APPARATUS.

` Specification forming part of Letters Patent No. 46,2S4i,dated-February 7, 1865.

To @ZZ whom it may concern,.-

Beitknown that we, Fnnnunicn AcWnnnR and WILLIAM H. GREENE, b oth ofWoonsocket, in thev county ot' Providence and State Of -Rhode Island,have invented an Improved Draft-Tube for Soda-Water Apparat-us; and

we do hereby declare that the following,

accompany and form part of this specification, is a description of ourinvention sui'- iicient to-enable those skilled inthe art to practiceit.

This invention relates vto the construction of the invention having for'its object t1e'=combination in one instrumentof the tube for drawingsirups and that'for drawing the aerated water in such manner that whilethe outlet of the main -tube is of sufficient size to allow the an innertube abovev its outlet is capable of being enlarged or diminished toregulate at pleasure the stream of 'soda or aerated water Our inventionconsists in the peculiar construction given to .the tube and itsa-ppendares for the purpose of regulatingthe ow of sirup and ofsoda-water. Y

' It is well known that great dilculty is ex perien'ced in thepreparation of beverages charged with carbonicacid gas, (generally in somixingthesirup and aerated water as to have the sirup andwaterproperlycornmingled andthebeverageat of the soda-water tube be sosmaIL'a's to give sufficient impetus to thoroughly mix" the sirup thelengthv of time taken to draw the same and its vcommotion or agitationin the glass liberates the gas and. renders the beverage nsipid.'l.It,-on the contrary, the aeratedwater isldrawn fina large rated' withit, and, although' the well-known chargingbottles :have heretofore beenemployed toa great extent, their use'is attended By our invention thesirup is rst drawn (the" sirup being shut oi') the size of the tubeabove the outlet is diminished 'and the aerated; water lthe tube ai.

to run from the lube with its'full headv in a very small stream, andafterward to run in an enlarged stream, and with its force broken ordiminished vthe enlarged strearn ruiming in a shower, the force ofwhichis regulated at pleasure.

Our invention is embodied in the drafttube shown in the drawings, Figurel'reprei senting a front view thereof', and Fig. 2 a side view, the tubebeing shown as broken to `eX- hibit its interior structure., Fig. 3 is avertical central and transverse section et the tube.

a denotes the outer casing or tube; b, the

innertube, which is a. continuation of oroutlet for the pipe c, which,with its branches,- eX- tends to the soda-fountain and sirupvessels.

The internal diameter of thetubeb is def creasedvat its 'lower end, asseen in Fig. 3, the

small size of the outlet or passa-ge d so made` being the most conduciveto"'the complete in terminglin g of the sirup with the soda-water 'whenthe Ylatter is discharged withy the full head ofthe fountain and throughthis aperture alone into a tumbler containing the Sirup. Just abov'ethis small passage in the tube b said tube is provided with two vlargelateral orifices, e, opening into the tube-a, the passage ddischarging'at the bottom of and beyond l These lateral orices e arecontrolled by a cylindrical or tubular gate, f,

which encircles or surrounds the tubeb and t seen in the drawings.

In preparing a beverage,

is connected with a stem, g, and handle h, as

the s irup isirst let into the pipe c and tube b, the gate f being'raised by its stem into the position seen in `Fig. 2, or to such extentas to allow the sirup' to freely flow through the tube b, apertures e,and tube a into the tumbler held or placed below. It"the sirupy be verythin, may be raised but little ,if at all,but generally it is preferableto let the sirup run with thewhole extent of outlet.v The handle histhen the gate depressed, (the sirup being previously cutoti",)` closingthe lateral apertures e, and the soda-water is let on. With the fullhead of the fountain the direct action of the stream issuingfrom theoutlet d commingles the lsirup and soda-water simultaneously with theircoutact, and the handle h being then raised, the

aerated water rushesl from the lateral orifices e, striking the edjacentinterior portion of the 'tube u yand thence falling into-'the tumblerwith a diminished force and without danger ot' liberating the gus withwhich it is charged.

The streams may, however, besilnultanecusly drawn from th e passage oroutlet d and through the ori'iiceseand tube b, the central streamthrouglrtsforce intermixing the `eeratedwater and s'virupywhile thesurrounding shower iusures tliejproper.impregnation or' aeration of thebeverage. A l

We are aware that it is` not new to vdraw soda-water from large andsmall outlets or in large and' small streams,jand also that it isl notnew to interrupt or yintercept its directl flow. Several arrangementsfor these purnoses have been devised, but'the construction l hereirdescribed and invented by us we vcousider to be the mest convenient andpractical for the satisfactory preparation ci' sodurwater beverages.

We claim- -v The cpustructicn of a draft tube for soda- Water apparatuswi ah an inner tube, b,l1aviug auL outlet., d, and lateral orifices e.opening into the tube a and controlled by a gate,f,

`the whole being' constructed and arranged to operate substantial-y asset forth. v
